This is the same infinite recursion bug that we need approval for
committing. When approval is given, it will be committed, and the bug will
be fixed.
Look at gdb-patches for a recent message from Jim Ingham for the most
recent patch for this bug, and apply. It's been pissing people off for
over a month
now, but there is little that can be done, as their is no obvious bugfix
rule, as there in in gcc.
